"Our treasure no man taketh from us," he replied. "This he gave us, this he left with us: not as the world giveth, gave he unto us."

"But can nothing you yourselves do, or omit to do, spoil or dim your jewel?" I resumed.

His brow saddened.

"Alas! There and there only have our enemies any real strength against us," he replied. "Sorrows only add to its lustre; in the loss of everything else it only shines the brighter; hunger and thirst but prove the unfailing nature of the fountain in the crystal vase; destitution and darkness, dungeons and tortures, only make the bright visions of our telescope more glorious; but we, we ourselves may indeed dim its lustre, or, if we will, yield it up altogether."

"All this is natural and comprehensible," I said. "The dungeon must make the jewel brighter; the drought, the unfailing spring more precious; the narrowing of all prospects here, enhance the visions of that magic glass; the cruelties of the usurper, endear the sight of the Prince you serve."

"This the wisest of our enemies have found out," the old man replied. "They find that nothing they can do harms us, but only what they can make us do ourselves; and to this they direct their efforts."

"In what way?" I inquired.

"In many ways," he answered, sadly. "The jewel, which nothing external can dim, is sensitive to the least change in us. Any infringement of our King's laws, or, especially, any unfaithfulness to our King, dims its lustre at once; any drinking of these forbidden cups of intoxication dries up the crystal fountain; any yielding to the usurper's service blots out from our magic glass its glorious visions, and the sight of our King in his beauty."

"Are there any other dangers?" I inquired.

"Countless dangers," he replied. "Especially three devices have been found too successful against us. Our jewel only keeps bright with use, and in three ways our enemies endeavour to deter us from using it. The timid they threaten, and induce to hide it from fear: and the cowardly concealing of our treasure inflicts on us two evils: it prevents our winning by it fresh followers to our Prince; and in concealment the jewel itself invariably grows dim. The young and careless they engage in the ambitious pursuits or the gay amusements of the court, until they forget to use the precious gem, and in ceasing to use it, they necessarily cease to shine with its light, and grow like any of the usurper's train.
